Hamshack.ca is a work-in-progress project intended to fulfil a need for a consolidated, more robust swap and shop site for use by licenced Canadian amateur radio operators.  With this in mind, we’re always looking to improve the site. So, if you have ideas that you’d like to see implemented use the Contact Form to send a note and I’ll do my best to include your suggestions in future releases. Also, if you run across a ‘bug’ or other minor ‘nit’ I’d like to hear from you. 73 – VE7DXE (Don)
